Field Classes

All field classes and herb walks are led by Heather Luna, clinical herbalist and herbal educator of over twenty years. She holds a wealth of knowledge in the uses and applications of both local flora and herbs of commerce. 

Field Classes & herb walks are held outdoors at various locations throughout the Nevada County area. Class locations range from the cozy nest of our school Medicine Garden to various treasured trails and forests in the wild landscape of the Sierra foothills. We will learn botanical identification and uses of medicinal and edible plants in their local habitats. Enjoy a gentle hike into the beautiful, wild forest landscape to meet and discuss the local plant life. 

These gatherings are rich botanical adventures which strengthen our relationships to the plants and the use of herbs in our daily lives. Due to the variation of ecosystems and activities held at each field class throughout the season every stand-alone class is a unique experience that cannot reflect the entirety of outdoor adventures we will embark throughout the year. These inspirational botanical play days are for every level of herbalist, from beginner to professional.
